Evaluation of the Effect of Venous Diameter Measurement by Ultrasonography on Pain and Withdrawal Response (VDIAMETER)

16. desember 2017 oppdatert av: SİNAN YILMAZ, Aydin Adnan Menderes University

During general anesthesia, intravenous (IV) medications can disrupt the patient's comfort by causing a pain sensation or a withdrawal response in the heart. Propofol and rocuronium are among the most common causes of this condition.

In recent years, the use of ultrasonography (USG) in anesthesia has become widespread with the rapid advancement of technology. The use of the patient's head is a non invasive method.

This study is aimed to evaluate whether the size of the venous diameter assessed by ultrasonography in our study is an effect on pain and withdrawal response after drug injections.

Detaljert beskrivelse

The study was conducted in patients who underwent surgical procedures under general anesthesia by obtaining consent from the Adnan Menderes University Medical Faculty Ethics Board and written consent from the patients and then being admitted to the ASA I-II age group 18-70 years of age.

Patients with peripheric vascular disease, vasculitis, rheumatologic disease, non-cooperative, under the age of 18 and over 70, ASA III and above, allergic to general anesthetic agents and refusing to participate in the study were excluded from the study.

Studiepopulasjon

The study was conducted on 145 patients aged 17- 70 years of ASA (American Society of Anesthesiologists) physical status I- II who were to undergo various elective operations. None of the patients was premedicated before the operation. Venous diameter measurements were performed in preoperative room via USG.The patients were monitored with three derivation electrocardiogram, non- invasive arterial pressure, and pulse oximeter.

Kohorter og intervensjoner

Gruppe / Kohort
Intervensjon / Behandling
Group 1

Venous diameter measurements were made via the USG in the hand dorsum. Transverse venous diameter ≤2mm was defined group 1.

Anesthesia induction drugs were all treated in the same order and dose. Pain score, withdrawal movement score and hemodynamic response was recorded.
Diagnostisk test: Pain Score

Four poin scala 0=No Pain

  1. mild
  2. intermediate
  3. severe
Diagnostisk test: Withdrawal movement score

Withdrawal movements

  1. no movement response
  2. movement limited to the wrist
  3. movement limited to the elbow/shoulder,
  4. generalized movement response.
Diagnostisk test: hemodynamic response
Hemodynamic data were recorded in the patients taken in the operation room. (T0). Hemodynamic values (T1) measured 1 minute after administration of intravenous propofol were recorded. Hemodynamic values (T2) measured 1 minute after administration of intravenous rocuronium were recorded. Hemodynamic values (T3) measured 1 minute after administration of endotracheal intubation were recorded.
Group 2

Venous diameter measurements were made via the USG in the hand dorsum.Transverse venous diameter >2mm was defined group 2.Anesthesia induction drugs were all treated in the same order and dose.

Pain score, withdrawal movement score and hemodynamic response was recorded.
Diagnostisk test: Pain Score

Four poin scala 0=No Pain

  1. mild
  2. intermediate
  3. severe
Diagnostisk test: Withdrawal movement score

Withdrawal movements

  1. no movement response
  2. movement limited to the wrist
  3. movement limited to the elbow/shoulder,
  4. generalized movement response.
Diagnostisk test: hemodynamic response
Hemodynamic data were recorded in the patients taken in the operation room. (T0). Hemodynamic values (T1) measured 1 minute after administration of intravenous propofol were recorded. Hemodynamic values (T2) measured 1 minute after administration of intravenous rocuronium were recorded. Hemodynamic values (T3) measured 1 minute after administration of endotracheal intubation were recorded.
